Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, and in particular to a resin production mixing device and process for manufacturing a respirator wound composite gas cylinder. Background Art

[0002] In the manufacturing of wound composite gas cylinders for respirators, the mixing quality of resins is crucial to the performance of the gas cylinders. Traditional resin production mixing devices have problems such as uneven mixing and low efficiency. In addition, during the mixing process, resin residues are likely to remain on the inner wall of the container, which not only causes a waste of raw materials, but also affects the subsequent mixing quality. Therefore, it is of great practical significance to develop a production mixing device that can efficiently mix resins and reasonably scrape off the residues on the inner wall.

[0003] A mixing device for producing epoxy resin paint is disclosed in the patent publication number CN219701761U, which includes a barrel, a first feed pipe is fixedly connected to one side of the middle of the top surface of the barrel, a first valve is arranged in the middle of the first feed pipe, a second feed pipe is fixedly connected to the other side of the middle of the top surface of the barrel, a second valve is arranged in the middle of the second feed pipe, a motor is fixedly connected to the middle of the top surface of the barrel, the output end of the motor is fixedly connected to the top of the stirring rod, the outer side of the bracket is fixedly connected to the bottom of the inner wall of the barrel, and a discharge pipe is fixedly connected to the bottom of the barrel. In the utility model, two or more raw materials can be poured into the interior of the barrel through the first feed pipe and the second feed pipe, and when the raw materials enter the barrel and hit the stirring rod, the two raw materials also hit each other, thereby completing preliminary mixing and accelerating the mixing rate.

[0004] The prior art has the following defects: Unable to scrape off the residues on the stirring blades and tank walls in time: After the device has been running continuously, a large amount of resin residue will adhere to the stirring blades and tank walls. As time accumulates, these residues continue to thicken, resulting in a significant decrease in stirring efficiency and poor uniformity of the mixed resin. In addition, the residual resin will gradually mix into the new material during subsequent mixing, affecting product quality and making it difficult for the performance of the respirator-wrapped composite gas cylinder to meet standards. Therefore, it is necessary to set up a structure to scrape off the residues on the stirring blades and tank walls. The stirring blades can continuously maintain good stirring performance, making resin mixing more efficient. At the same time, it can reduce the corrosion and wear of the equipment due to residue accumulation, extend the service life of the device, and achieve the effect of improving product quality and reducing maintenance costs.

[0005] The mixing method is too single, resulting in low mixing efficiency: Most existing devices rely on stirring in a single direction or form, which cannot form multi-dimensional material flow and cannot fully drive the resin in every corner to participate in the mixing, resulting in poor mixing effect and low efficiency, which greatly prolongs the mixing time. The material that should have been quickly and evenly mixed still has local unevenness after long-term stirring. Therefore, it is necessary to set up a variety of stirring structures in different directions and types to reduce the mixing time, quickly reach the ideal mixing state, and achieve the effect of improving production efficiency and reducing energy consumption. Summary of the invention

[0006] In view of the problems in the prior art such as the inability to timely scrape off the residues on the stirring blades and the tank wall and the low mixing efficiency due to the single stirring method, a resin production mixing device and process for manufacturing a respirator wrapped composite gas cylinder is proposed.

[0007] The present application provides a resin production mixing device for manufacturing respirator wrapped composite gas cylinders, the purpose of which is to scrape off the residues on the stirring blades and the tank wall through the provided stirring mechanism and scraper assembly, so that the stirring blades can continuously maintain good stirring performance, making the resin mixing more efficient, and at the same time, reducing the corrosion and wear of the equipment due to the accumulation of residues, extending the service life of the device, and achieving the effect of improving product quality and reducing maintenance costs. In addition, through stirring in a variety of different directions and types, the mixing time can be reduced, and the ideal mixing state can be quickly achieved, thereby achieving the effect of improving production efficiency and reducing energy consumption.

[0008] The technical scheme of the present invention is: a resin production mixing device for manufacturing a respirator wound composite gas cylinder, comprising a bracket, a shell component fixedly installed above the bracket, a fixing part and a servo motor sequentially arranged on the top of the shell component, and a stirring mechanism and a scraper mechanism arranged inside the shell component, the shell component comprising a feeding top cover and a mixing tank sequentially connected to the bottom of the fixing part, the stirring mechanism comprising a stirring shaft sleeved on the output shaft of the servo motor, a plurality of tank wall scrapers fixedly connected to the outer wall of the stirring shaft, and a plurality of stirring blades respectively fixedly connected to the outer walls of the plurality of tank wall scrapers; The scraper mechanism includes a driving assembly arranged on the outer wall of the stirring shaft, and a lifting assembly arranged inside the driving assembly. The lifting assembly includes a plurality of sliding rods slidably connected to the inner wall of the driving assembly. The bottom of each sliding rod is fixedly connected to a connecting rod of different lengths. The bottom of the connecting rod is connected to a double-sided scraper that can scrape off residues on the front and back sides of the stirring blade.

[0009] By adopting the above scheme, through the setting of the stirring mechanism and scraper mechanism, the output shaft of the servo motor drives the stirring shaft to rotate. When the stirring shaft rotates, the tank wall scraper will scrape along the inner wall of the mixing tank to prevent the resin from adhering to the tank wall and ensure uniform mixing. The stirring blades are driven by the stirring shaft to fully stir the resin and additives to make them fully mixed. During the stirring process, the sliding rod can be raised and lowered through the output of the driving component, and the double-sided scrapers driven by connecting rods of different lengths can scrape off the residues on the front and back sides of the stirring blades.

[0010] Furthermore, the driving assembly includes a sun gear fixedly connected to the outer wall of the stirring shaft, and the outer periphery of the sun gear is meshed with a plurality of planetary gears with equal spacing, and the inner wall of each planetary gear is slidably connected to the corresponding sliding rod.

[0011] By adopting the above scheme, the sun gear rotates with the stirring shaft through the setting of the driving assembly. Since the sun gear is engaged with multiple planetary gears, it will drive the planetary gears to rotate around the sun gear, and the sliding rod can slide inside the planetary gears.

[0012] Furthermore, a connecting frame is fixedly connected between the outer walls of the plurality of connecting rods, and a telescopic spring is connected between the top of each connecting rod and the bottom of the corresponding planetary gear.

[0013] Furthermore, a first contact head and a second contact head are fixed to the tops of two of the slide bars respectively, and a guide block is fixed to the tops of the remaining slide bars, and each guide block can slide on the inner wall of the corresponding planetary gear.

[0014] By adopting the above scheme, through the setting of the lifting assembly, the connecting frame firmly connects multiple connecting rods to ensure the synchronous movement of each connecting rod. When the planetary gear rotates, the first contact head and the second contact head on the two sliding rods are affected by the specific structure to drive the sliding rod to do lifting movement. The guide blocks on the top of the remaining sliding rods slide on the inner wall of the planetary gear to play a guiding role to ensure stable movement. The telescopic spring is buffered and adjusted to make the double-sided scraper in good contact with the stirring blade, so that the residue is scraped off in time and the resin mixture is improved.

[0015] Furthermore, the drive assembly also includes a fixed gear ring meshing with the periphery of multiple planetary gears, the outer wall of the fixed gear ring is connected to a fixed frame, the top of the fixed frame is connected to a fixed block, the inner wall of the fixed block is provided with an extrusion groove, and the tops of the first contact head and the second contact head are both slidably matched with the inner wall of the extrusion groove.

[0016] By adopting the above scheme, the driving component is set up, the fixed ring gear is engaged with the outer periphery of the planetary gear, and the position is fixed by the fixed frame and the fixed block. During the rotation of the planetary gear, the first contact head and the second contact head on the top of the slide rod slide in the extrusion groove on the inner wall of the fixed block. Due to the special shape of the extrusion groove, a force is generated on the first and second contact heads, causing the slide rod to move up and down, thereby allowing the double-sided scraper to clean the stirring blades to ensure the resin mixing effect.

[0017] Furthermore, a connecting component is arranged between the fixed block and the fixed member, and the connecting component includes a second slide groove and a first slide groove which are respectively opened inside the fixed block and the fixed member, and a plurality of connecting blocks are slidably connected between the inner walls of the second slide groove and the first slide groove, and the plurality of tank wall scrapers are evenly distributed between the plurality of connecting blocks.

[0018] By adopting the above scheme, through the setting of the connecting component, the second slide groove corresponds to the first slide groove, the shape design of the connecting block is adapted to the slide groove, the surface of the connecting block is smooth, and the friction with the inner wall of the slide groove is extremely small, thereby ensuring the smoothness of its sliding. When the tank wall scraper rotates, it pushes the connecting block to slide in the slide groove, thereby maintaining the connection between the fixed block and the fixed part.

[0019] Furthermore, a discharge valve is fixedly connected to the bottom of the mixing tank, and a stirring auger located directly above the discharge valve is also fixedly connected to the outer wall of the stirring shaft.

[0020] Furthermore, a heating barrel is fixedly connected to the outer wall of the mixing tank, the outer wall of the heating barrel is fixedly connected to the bracket, and two heating elements for heating and temperature control are fixedly connected to the bottom of the heating barrel.

[0021] By adopting the above scheme, through the setting of the outer shell assembly, when the two heating elements at the bottom of the heating barrel are turned on, the heating elements will generate heat and transfer it to the mixing tank through the heating barrel, heating the resin in the tank and accurately controlling the temperature. After the stirring is completed, the discharge valve is opened to discharge the mixed resin smoothly from the mixing tank.

[0022] Another aspect of the present application provides a production process of a resin production mixing device for manufacturing a respirator wrapped composite gas cylinder, using a resin production mixing device for manufacturing a respirator wrapped composite gas cylinder, comprising the following steps: Step 1: Wrap the respirator around the composite gas cylinder to make the required resin and additives, and put them into the mixing tank through the feeding top cover; Step 2: Turn on the heating element to heat the resin in the mixing tank through the heating barrel and control the temperature; Step 3: Start the servo motor, and the stirring shaft drives the tank wall scraper, stirring blades and stirring auger to stir; Step 4: During the stirring process, the stirring blade rotates forward 270°, and the double-sided scraper rotates reversely 90° to scrape off the residue on the upper and lower surfaces of the stirring blade in turn; Step 5: Then the stirring blades are reversed 540°, the double-sided scrapers are rotated 180° forward to reset, and the cycle is repeated; Step 6: After the mixing is completed, open the discharge valve and the servo motor will continue to run repeatedly until the discharge is completed.

[0023] By adopting the above scheme, the resin and additives required for the manufacture of the respirator wrapped composite gas cylinder are put into the mixing tank through the feeding top cover through the setting of the stirring mechanism and the scraper mechanism, the two heating elements at the bottom of the heating barrel are turned on, the heating elements generate heat and transmit it to the mixing tank through the heating barrel, the resin in the tank is heated and the temperature is accurately controlled, the servo motor is started, and the output shaft of the servo motor drives the stirring shaft to rotate. When the stirring shaft rotates, the tank wall scraper will scrape along the inner wall of the mixing tank to prevent the resin from adhering to the tank wall and ensure uniform mixing. The stirring blades are driven by the stirring shaft to stir the resin and additives. The additives are fully stirred to make them fully mixed. The stirring auger can promote the flow of resin at the bottom during the stirring process to avoid sedimentation and uneven mixing at the bottom. During the stirring process, the stirring blade rotates 270° forward and the double-sided scraper reverses 90° to scrape off the residues on the upper and lower surfaces of the stirring blade in turn. Then the stirring blade reverses 540° and the double-sided scraper rotates 180° forward to reset. Repeat this cycle. After the stirring is completed, open the discharge valve. At this time, the servo motor continues to run repeatedly and the stirring auger continues to rotate to discharge the mixed resin smoothly from the mixing tank until the discharge is completed.

[0024] Beneficial effects of the present invention: Through the provided stirring mechanism and scraper mechanism, the output shaft of the servo motor drives the stirring shaft to rotate. When the stirring shaft rotates, the tank wall scraper will scrape along the inner wall of the mixing tank to prevent the resin from adhering to the tank wall and ensure uniform mixing. Driven by the stirring shaft, the stirring blade fully stirs the resin and additives to make them fully mixed. During the stirring process, the slide rod can be raised and lowered through the output of the driving component, and the double-sided scrapers driven by connecting rods of different lengths scrape off the residues on both sides of the stirring blades. The stirring blades can continuously maintain good stirring performance, making the resin mixing more efficient. At the same time, the corrosion and wear of the equipment due to the accumulation of residues is reduced, the service life of the device is extended, and the effect of improving product quality and reducing maintenance costs is achieved.

[0025] Through the setting of the lifting assembly, the connecting frame firmly connects multiple connecting rods to ensure the synchronous movement of each connecting rod. When the planetary gear rotates, the first contact head and the second contact head on the top of the slide rod slide in the extrusion groove on the inner wall of the fixed block. Due to the special shape of the extrusion groove, a force is generated on the first and second contact heads, causing the slide rod to move up and down. The guide blocks on the top of the remaining slide rods slide on the inner wall of the planetary gear to guide and ensure stable movement. The telescopic spring is buffered and adjusted to make the double-sided scraper in good contact with the stirring blade, so that the residue is scraped off in time and the resin mixing quality is improved.

[0026] Through the setting of the connecting component, the second slide groove corresponds to the first slide groove, the shape design of the connecting block is adapted to the slide groove, the surface of the connecting block is smooth, and the friction with the inner wall of the slide groove is extremely small, thereby ensuring the smoothness of its sliding. When the tank wall scraper rotates, it pushes the connecting block to slide in the slide groove, thereby maintaining the connection between the fixed block and the fixed part.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1 - Fig.13 , which is the first embodiment of the present invention, provides a resin production mixing device for manufacturing a respirator wrapped composite gas cylinder, including a bracket 1, a shell component 4 fixedly installed above the bracket 1, a fixing part 3 and a servo motor 2 sequentially arranged on the top of the shell component 4, and a stirring mechanism 5 and a scraper mechanism 6 arranged inside the shell component 4, the shell component 4 includes a feeding top cover 41 and a mixing tank 42 connected to the bottom of the fixing part 3 in sequence, the stirring mechanism 5 includes a stirring shaft 52 sleeved on the output shaft of the servo motor 2, a plurality of tank wall scrapers 53 fixedly connected to the outer wall of the stirring shaft 52, and a plurality of stirring blades 54 respectively fixedly connected to the outer walls of the plurality of tank wall scrapers 53.

[0031] Reference Figure 4 - Fig. 9 The scraper mechanism 6 includes a driving assembly 62 arranged on the outer wall of the stirring shaft 52, and a lifting assembly 63 arranged inside the driving assembly 62. The lifting assembly 63 includes a plurality of slide rods 637 slidably connected to the inner wall of the driving assembly 62. The bottom of each slide rod 637 is fixedly connected to a connecting rod 634 of different lengths. The bottom of the connecting rod 634 is connected to a double-sided scraper 635 that can scrape off the residue on the front and back sides of the stirring blade 54.

[0032] Specifically, the tank wall scraper 53 can scrape along the inner wall of the mixing tank 42 during the stirring process to prevent the resin from adhering to the tank wall, thereby ensuring the uniformity of the resin mixing. The stirring blade 54 can fully mix the resin and additives in the mixing tank 42 under the drive of the stirring shaft 52. The driving component 62 is arranged on the outer wall of the stirring shaft 52. It can convert the rotation of the stirring shaft 52 into a specific form of motion to provide power support for the operation of the lifting component 63. During the stirring process, with the lifting and lowering movement of the sliding rod 637, the double-sided scraper 635 can clean the resin attached to the stirring blade 54 in time to ensure the stirring effect of the stirring blade 54, thereby improving the quality of the resin mixing.

[0033] Through the provided stirring mechanism 5 and scraper mechanism 6, the output shaft of the servo motor 2 drives the stirring shaft 52 to rotate. When the stirring shaft 52 rotates, the tank wall scraper 53 will scrape along the inner wall of the mixing tank 42 to prevent the resin from adhering to the tank wall and ensure uniform mixing. The stirring blade 54 is driven by the stirring shaft 52 to fully stir the resin and additives to make them fully mixed. During the stirring process, the slide rod 637 can be raised and lowered through the output of the driving component 62, and the double-sided scraper 635 driven by the connecting rod 634 of different lengths scrapes off the residues on the front and back sides of the stirring blade 54.

[0034] Reference Figure 6 - Figure 8 The driving assembly 62 includes a sun gear 624 fixedly connected to the outer wall of the stirring shaft 52, and the outer periphery of the sun gear 624 is meshed with a plurality of planetary gears 623 with equal spacing, and the inner wall of each planetary gear 623 is slidably connected to the corresponding sliding rod 637.

[0035] The sun gear 624 rotates along with the stirring shaft 52 through the drive assembly 62 . Since the sun gear 624 is meshed with the plurality of planetary gears 623 , the planetary gears 623 are driven to rotate around the sun gear 624 , and the slide bar 637 can slide inside the planetary gears 623 .

[0036] Reference Figure 8-Figure 9 A connecting frame 636 is fixedly connected between the outer walls of multiple connecting rods 634, and a telescopic spring 638 is connected between the top of each connecting rod 634 and the bottom of the corresponding planetary gear 623, wherein the tops of two sliding rods 637 are respectively fixed with a first contact head 631 and a second contact head 632, and the tops of the remaining sliding rods 637 are fixed with a guide block 633, and each guide block 633 can slide on the inner wall of the corresponding planetary gear 623.

[0037] Through the setting of the lifting component 63, the connecting frame 636 connects the multiple connecting rods 634 firmly to ensure the synchronous movement of each connecting rod 634. When the planetary gear 623 rotates, the first contact head 631 and the second contact head 632 on the two sliding rods 637 are affected by the specific structure to drive the sliding rod 637 to do lifting movement. The guide blocks 633 on the top of the remaining sliding rods 637 slide on the inner wall of the planetary gear 623 to guide and ensure stable movement. The telescopic spring 638 buffers and adjusts to make the double-sided scraper 635 in good contact with the stirring blade 54, so as to scrape off the residue in time and improve the resin mixing quality.

[0038] Reference Figure 7-Figure 10 The driving assembly 62 also includes a fixed gear ring 622 meshing with the periphery of multiple planetary gears 623. The outer wall of the fixed gear ring 622 is connected to a fixed frame 621, and the top of the fixed frame 621 is connected to a fixed block 61. The inner wall of the fixed block 61 is provided with an extrusion groove 639, and the tops of the first contact head 631 and the second contact head 632 are both slidably matched with the inner wall of the extrusion groove 639.

[0039] Through the set driving component 62, the fixed ring gear 622 is meshed with the outer periphery of the planetary gear 623, and the position is fixed by the fixed frame 621 and the fixed block 61. During the rotation of the planetary gear 623, the first contact head 631 and the second contact head 632 at the top of the slide bar 637 slide in the extrusion groove 639 on the inner wall of the fixed block 61. Due to the special shape of the extrusion groove 639, a force is generated on the first and second contact heads, causing the slide bar 637 to move up and down, thereby allowing the double-sided scraper 635 to clean the stirring blade 54 to ensure the resin mixing effect.

[0040] Reference Figure 6 A connecting assembly 51 is arranged between the fixed block 61 and the fixing member 3, and the connecting assembly 51 includes a second slide groove 513 and a first slide groove 512 which are respectively opened inside the fixed block 61 and the fixing member 3, and a plurality of connecting blocks 511 are slidably connected between the inner walls of the second slide groove 513 and the first slide groove 512, and a plurality of tank wall scrapers 53 are evenly distributed between the plurality of connecting blocks 511.

[0041] Specifically, the second slide groove 513 corresponds to the first slide groove 512, the shape design of the connecting block 511 is adapted to the slide groove, the surface of the connecting block 511 is smooth, and the friction with the inner wall of the slide groove is extremely small, thereby ensuring the smoothness of its sliding. When the tank wall scraper 53 rotates, it pushes the connecting block 511 to slide in the slide groove, thereby maintaining the connection between the fixed block 61 and the fixing member 3.

[0042] Reference Figure 2 - Figure 4A discharge valve 43 is fixedly connected to the bottom of the mixing tank 42, and a stirring auger 55 located directly above the discharge valve 43 is also fixedly connected to the outer wall of the stirring shaft 52. A heating barrel 44 is fixedly connected to the outer wall of the mixing tank 42, and the outer wall of the heating barrel 44 is fixedly connected to the bracket 1. Two heating elements 45 for heating and temperature control are fixedly connected to the bottom of the heating barrel 44.

[0043] Through the provided outer shell component 4, when the two heating elements 45 at the bottom of the heating barrel 44 are turned on, the heating elements 45 will generate heat and transfer it to the mixing tank 42 through the heating barrel 44, so as to heat the resin in the tank and precisely control the temperature. After the stirring is completed, the discharge valve 43 is opened to discharge the mixed resin smoothly from the mixing tank 42.

[0044] During use, the resin and additives required for the manufacture of the respirator wrapped composite gas cylinder are put into the mixing tank 42 through the feeding top cover 41, and the two heating elements 45 at the bottom of the heating barrel 44 are turned on. The heating elements 45 generate heat and transmit it to the mixing tank 42 through the heating barrel 44 to heat the resin in the tank and accurately control the temperature. The servo motor 2 is started, and the output shaft of the servo motor 2 drives the stirring shaft 52 to rotate. When the stirring shaft 52 rotates, the tank wall scraper 53 will scrape along the inner wall of the mixing tank 42 to prevent the resin from adhering to the tank wall and ensure uniform mixing. The stirring blade 54 is driven by the stirring shaft 52 to fill the resin and additives. The stirring auger 55 can promote the flow of resin at the bottom during the stirring process to avoid precipitation and uneven mixing at the bottom. During the stirring process, the stirring blade 54 rotates 270° forward and the double-sided scraper 635 reverses 90° to scrape off the residues on the upper and lower surfaces of the stirring blade 54 in turn. Then the stirring blade 54 reverses 540° and the double-sided scraper 635 rotates 180° forward to reset. This cycle is repeated. After the stirring is completed, the discharge valve 43 is opened. At this time, the servo motor 2 continues to run repeatedly, and the stirring auger 55 continues to rotate to discharge the mixed resin smoothly from the mixing tank 42 until the discharge is completed.

[0045] Example 2, reference Figure 1 - Fig.13 , provides a production process of a resin production mixing device for manufacturing a respirator wrapped composite gas cylinder, using a resin production mixing device for manufacturing a respirator wrapped composite gas cylinder, comprising the following steps: Step 1: wrap the respirator around the composite gas cylinder to make the required resin and additives, and put them into the mixing tank 42 through the feeding top cover 41; Step 2: Turn on the heating element 45 to heat the resin in the mixing tank 42 through the heating barrel 44 and control the temperature; Step 3: Start the servo motor 2, and the stirring shaft 52 drives the tank wall scraper 53, the stirring blade 54 and the stirring auger 55 to stir; Step 4: During the stirring process, the stirring blade 54 rotates forward 270°, and the double-sided scraper 635 rotates reversely 90° to scrape off the residues on the upper and lower surfaces of the stirring blade 54 in turn; Step 5: Then the stirring blade 54 is reversed 540°, and the double-sided scraper 635 is rotated 180° forward to reset, and this cycle is repeated; Step 6: After the mixing is completed, the discharge valve 43 is opened, and the servo motor 2 continues to run repeatedly until the discharge is completed.

[0046] Working principle of the present invention: During operation, the resin and additives required for the manufacture of the respirator wrapped composite gas cylinder are put into the mixing tank 42 through the feeding top cover 41, and the two heating elements 45 at the bottom of the heating barrel 44 are turned on. The heating elements 45 generate heat and transfer it to the mixing tank 42 through the heating barrel 44, so as to heat the resin in the tank and accurately control the temperature, thereby providing suitable temperature conditions for subsequent mixing and stirring, and ensuring that the resin has good fluidity and mixing effect.

[0047] Start the servo motor 2, and the output shaft of the servo motor 2 drives the stirring shaft 52 to rotate. When the stirring shaft 52 rotates, the tank wall scraper 53 will scrape along the inner wall of the mixing tank 42 to prevent the resin from adhering to the tank wall and ensure uniform mixing. The stirring blade 54 is driven by the stirring shaft 52 to fully stir the resin and the additive to make them fully mixed. The stirring auger 55 can promote the flow of the resin at the bottom during the stirring process to avoid precipitation and uneven mixing at the bottom.

[0048] During the stirring process, the sun gear 624 in the driving assembly 62 rotates with the stirring shaft 52. Since the sun gear 624 is meshed with multiple planetary gears 623, the planetary gears 623 are driven to rotate around the sun gear 624. The inner wall of the planetary gear 623 is slidingly connected to the slide rod 637, and the first contact head 631 and the second contact head 632 at the top of the two slide rods 637 are slidingly matched with the extrusion groove 639 on the inner wall of the fixed block 61.

[0049] The stirring blade 54 rotates 270° forward, and the slide rod 637 drives the double-sided scraper 635 to reverse 90°. At this time, the first contact head 631 and the second contact head 632 are not in contact with the extrusion groove 639. The double-sided scraper 635 is located above the stirring blade 54 to scrape off the residue on the upper surface of the stirring blade 54.

[0050] The stirring blade 54 continues to rotate forward 270°, and the double-sided scraper 635 reverses 90°. At this time, the first contact head 631 and the second contact head 632 move downward in cooperation with the extrusion groove 639, and the double-sided scraper 635 rotates to the bottom of the stirring blade 54 to scrape off the residue on the lower surface of the stirring blade 54.

[0051] Then the stirring blade 54 is reversed by 540°, and the double-sided scraper 635 is rotated forward by 180° to reset, and this cycle is repeated to ensure the cleaning of the stirring blade 54 and improve the stirring effect.

[0052] After the stirring is completed, the discharge valve 43 is opened. At this time, the servo motor 2 continues to run repeatedly, and the stirring auger 55 continues to rotate to smoothly discharge the mixed resin from the mixing tank 42 until the discharge is completed.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
